Saturn

• Saturn is 95 times the size of Earth.
• Due to its low density Saturn would float in water (if it didn't dissolve).
• Saturn's rings are made mostly of billions of chunks of ice, ranging from microscopic to several metres in size. They were probably formed from a disrupted moon. The rings are less than 1km thick.
• Replenished from different sources, eg comets, meteors, moons. Chunks range in size from pebble to room-size.
• Minor moons in rings create interesting effects.
• The rings change constantly, and will eventually disappear.
• Its biggest moon, Titan, is the only known moon to have an atmosphere and liquid on the surface (liquid methane).
• The North pole hexagon is larger than Earth.
• Saturn has such low density that it would float in water (if you could find a big enough body of water and keep the planet from dissolving).
• Saturn has been visited by Pioneer 11 (1979), Voyagers (1980 & 1981) and Cassini.
